The musculoskeletal system forms the foundation for our mobility and stability. Pain in muscles, joints, or the spine is widespread and can have very different causes. They range from temporary overexertion and tension to injuries or illnesses.
Disorders of the musculoskeletal system can affect mobility, everyday life, and well-being. This article provides an overview of the structure of the musculoskeletal system, potential causes of discomfort, as well as general ways to support musculoskeletal health.
Foundation of movement: Structure and function of the musculoskeletal system
The musculoskeletal system – also known as the locomotor system – consists of an active and a passive part. The active musculoskeletal system includes, in particular, muscles and tendons. They enable movement and contribute to body posture. Fasciae and other connective tissue structures surround and connect numerous structures of the body.
The passive musculoskeletal system includes, among other things, bones and joints. They provide the body with structure and stability and, together with the active musculoskeletal system, form the foundation for our mobility.
Joints enable movements such as bending, stretching, or rotating. Tendons connect muscles to bones and transmit the force generated by the muscles.
The spine forms the central axis of the torso. It consists of 24 movable vertebrae as well as the sacrum and coccyx. Between the movable vertebrae are intervertebral discs that contribute to the flexibility and distribution of loads on the spine.
Why does the musculoskeletal system hurt? An overview of common causes
The causes of pain in the musculoskeletal system are diverse. Complaints can occur, for example, in connection with overexertion, injuries, degenerative changes, inflammatory diseases, or altered pain processing.
Degenerative changes can affect joints and the spine, among others. In osteoarthritis, the articular cartilage changes, and over time, other structures of the joint may also be affected. Osteoporosis is characterized by reduced bone density and is associated with an increased risk of bone fractures. Spondylosis refers to degenerative changes in the spine.
Inflammatory diseases can also cause musculoskeletal complaints. These include, for example, rheumatoid arthritis, an inflammatory-rheumatic autoimmune disease that primarily affects the joints.
Mechanical stress can occur, for instance, during unfamiliar or repetitive movements, prolonged static postures, or physical overexertion. Individual physical condition and load management also play a role.
Injuries from falls, accidents, or sports activities can cause acute pain and affect muscles, tendons, ligaments, joints, or bones.
Myofascial complaints affect muscles and the fasciae surrounding them. This can lead to localized pressure-sensitive areas and radiating discomfort.
Chronic pain syndromes are complex and can be accompanied by changes in pain processing. One example is fibromyalgia, where chronic, widespread pain often occurs together with other symptoms such as sleep problems or fatigue.
Since pain can have different causes and several factors can play a role simultaneously, medical clarification is advisable, especially for persistent or severe symptoms.
Not all pain is the same: Types, progression, and perception
Pain can be perceived in very different ways – for example, as pulling, stabbing, dull, burning, or radiating. The type, intensity, and location can provide clues for medical assessment but usually do not allow for a definitive diagnosis on their own.
Acute pain occurs, for example, in connection with an injury or temporary overexertion. Chronic pain is spoken of when symptoms persist over a longer period or occur repeatedly. In cases of chronic pain, changes in pain processing can play a role in addition to physical factors.
A description that is as precise as possible is helpful for medical assessment. This includes, for example:
- Type and intensity of the pain
- Exact location
- Onset and duration
- Frequency and time of day
- Occurrence at rest or during movement
- Possible radiation
- Factors that increase or decrease the discomfort
A pain diary can also help to record changes and potential correlations over a longer period.
Pain perception is influenced by numerous factors. These can include, among others, stress, sleep, mood, physical activity, and individual experiences. Conversely, long-lasting pain can impair psychological well-being and quality of life.
What you can do yourself: Exercise, nutrition, and relaxation
Regular physical activity generally contributes to health and physical well-being. Which form of exercise is suitable depends on the individual situation, fitness level, and any existing complaints.
In everyday life, it can be useful to regularly interrupt long phases in the same posture and to alternate between different forms of exercise. Sufficient recovery phases are also part of balanced load management.
Relaxation techniques such as breathing exercises, yoga, or progressive muscle relaxation can help promote physical and mental relaxation. Heat, cold, or massages are also frequently used as supportive measures. In the case of existing illnesses or unclear complaints, it should be clarified individually which applications are suitable.
A varied and balanced diet provides the body with energy, vitamins, minerals, and other dietary components. Vegetables, fruits, whole grain products, legumes, nuts, and suitable vegetable oils can be part of a balanced diet.
Sufficient sleep and recovery phases are also important components of a health-conscious lifestyle.
Nutrients and the musculoskeletal system
Various vitamins and minerals fulfill normal functions in the human body. These include, for example:
-
Vitamin D contributes to the maintenance of normal bones and normal muscle function.
-
Calcium is needed for the maintenance of normal bones.
-
Magnesium contributes to normal muscle function.
-
Vitamin C contributes to normal collagen formation for the normal function of cartilage and bones.
-
Manganese contributes to the maintenance of normal bones and normal connective tissue formation.
A balanced and varied diet forms the basis for the supply of nutrients.
Dietary supplements can complement the diet but do not replace a varied and balanced diet or a healthy lifestyle. Whether supplementation is useful in an individual case depends, among other things, on diet, life situation, and personal needs.
When should complaints be medically clarified?
Medical clarification is particularly useful in case of:
- severe, persistent, or increasing pain
- noticeable swelling or redness
- pronounced or newly occurring limitations in movement
- pain after an accident or injury
- fever or a clear feeling of illness associated with pain
- newly occurring neurological symptoms such as numbness, paralysis, or pronounced muscle weakness
A medical or therapeutic assessment may also be useful for existing illnesses or recurring complaints.
Depending on the cause, different treatment approaches may be required. These can include, for example, medical treatment, physiotherapy, exercise therapy, or other therapeutic measures.
Conclusion: Supporting the musculoskeletal system in everyday life
The musculoskeletal system is a complex interplay of bones, joints, muscles, tendons, and other tissue structures. Complaints can consequently have different causes.
Regular physical activity, sufficient recovery, a varied and balanced diet, and a conscious approach to physical strain are important components of a health-oriented lifestyle.
In the case of long-lasting, severe, or unclear complaints, the cause should be medically clarified.
